Can Less Be More?
With its higher strength and improved performance characteristics, high-performance steel is indeed an alluring materials. Its cost, however, also is higher, a factor that cannot be ignored....
Initial Considerations
The purpose of this section is to aid the line designers in developing their specifications for fiber-reinforced polymer (FRP) materials utilized in electric overhead line structures....
Materials and Manufacturing Processes
This chapter introduces the basic materials used in the manufacturing of composite structures. It will help the line designer in understanding how the different elements of the fiber-matrix...
Design Loads
This chapter discusses the types of loadings that should be considered when designing overhead power lines utilizing fiber-reinforced polymer (FRP) poles. For infrastructure applications...
Performance-Based Criteria for FRP Products and Materials
In most ways, fiber-reinforced polymer (FRP) structures perform similar to wood and steel structures. There are, however, certain differences and these differences are described in this...
Suggested Guidelines for Performance-Based Tests
Although several standard tests are cited in this chapter, these tests are not designed specifically for fiber-reinforced polymer (FRP) overhead line structures. There are, in fact, no...
Quality Assurance
The user is responsible for ensuring the quality of products purchased. Therefore, the user of fiber-reinforced polymer (FRP) products determines the level of quality that will be accepted....
Assembly and Erection
This chapter is intended to provide recommendations on transporting, handling, assembling, and erecting fiber-reinforced polymer (FRP) poles. An important consideration is that FRP poles...
In-Service Considerations
Generally, little or no preventative maintenance is required on fiber-reinforced polymer (FRP) poles. This chapter discusses factors that could affect the performance of FRP poles after...

Evaluation of the Maccaferri Terramesh System Retaining Wall
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF/IIEC Innovation Center. This report describes a HITEC evaluation designed...
Crossing the Yangtze
The Nanjing Second Yangtze River Bridge, which links two parts of the city of Nanjing, features the first use of an epoxy asphalt deck pavement in China and one of the longest cable-stayed...
Predicted Service Life of Armor Stone: A Case History
Laboratory testing for determination of true rock quality in terms of expected performance is not clear-cut, may be misleading, and requires extensive interpretation by an expert. This...
Effect of Aluminum Compression on ACSR Conductor Sags at High Operating Temperatures
Deregulation and restructuring are sweeping the electric utility industry in the United States. As a result, many utility engineers are analyzing, re-rating, and upgrading their most critical...
Use of New Liner In Water Distribution System
For years there has been interest in rehabilitation of water distribution systems to provide quality drinking water and to reduce breaks in the water system service. Much work has been...
Making the Most of HPC
Developing high-performance concrete (HPC) was only the first step toward bringing a material with improved durability, strength, constructability, and mechanical properties to the bridge...
Modeling of Inelastic Behavior of RC Structures under Seismic Loads
Proceedings of the U.S.?Japan Seminar on Post-Peak Behavior of Reinforced Concrete Structures Subjected to Seismic Loads: Recent Advances and Challenges on Analysis and Design, held in...
Symptom-Based Reliability of Aging Infrastructure Systems
Ideally, aging infrastructure systems should be monitored for safety and repaired in case of need. Eventually, authors believe that symptom-based reliability will be useful for safety...
Maintenance of Diaphragm-Girder Connections
Fatigue cracking at diaphragm-girder connections and at similar connections of cross-frames and floorbeams have been common in steel highway bridges for the past 20 or 30 years. Fatigue...
New Concepts in Structural Strength Assessment for Large Buildings in Fire
This paper presents theoretical descriptions of the key phenomena that govern the behaviour of composite framed structures in fire. These descriptions have been developed in parallel with...
